CARBURETER.

SPECIFICATION formingpart of Letters Patent No. 223,582, dated January 13, 1880.

Application filed November 29, 1879.

To all whom it may concern Be it known that 1,-HENRY C. DEVVI'LT, of

Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Garburetcrs; and I do hereby declare that the following is a full and exact description of the same, having reference to the accompanying drawings, wherein- Figure l is a longitudinal section of my carbureter. Fig. 2 is a transverse section of the same. Fig. 3 is a longitudinal section, showing a modified structure; and Fig. 4 is a transverse section of the same,

Garbureters have heretoforebeen constructed with devices for pumping or elevating the liquid hydrocarbon from the fiuid mass in the bottom of thecarbureter, and discharging the same upon absorbent material through which the air-current is forced and carbureted by absorption of the volatile. portions of said liquid; but the absorbent material retains within its fibers portions of said liquid, which finally become thick and gummy, and the volatility of the mass is diminished thereby, until finally it becomes non-volatile at the temperature of the air. This result does not take place when the liquid hydrocarbon is continuously exposed to the passing current of air in the form or condition of shower or spray without the intervention of absorbent material, or when absorbent material merely forms a surface or coating to retard the flow of the liquid hydrocarbon over a non-absorbent surface.

My invention therefore consists in a cylih- .der provided with an inner perforated shell formed in compartments, whereby the liquid hydrocarbon is continually withdrawn from theliquid mass at IiIlbOtlZ-OID of the carbureter,

and passed through the current of air in the form of shower or spray.

It also consists in a fibrous or absorbent coating or covering for the non-absorbent surfaces of the grating within the carbureter to retain the flow of the liquid hydrocarbon over the surfaces of the same.

That others may fully understand the construction and operation of the device shown in the accompanying drawings, designed to give effect to my invention, I will particularly describe the same, without, however, designor wings, G, are therefore similar to those h ere tofore in use; but between thevanes, and next the periphery of the cylinder A, inside thereof, I place other wings, (J G,which join the radial wings at a little distance inward from the periphery of the case, and at their opposite edges they approach or join the peripheral inclosure ofthe cylinder A, thus forming an inner case, between which and the outer case are spaces a, which fill with liquid hydrocarbon at each revolution of the cylinder A. The wings O are perforated along their free margin for a distance equal to half their width, or thereabout, and the liquid which is taken up behind them is poured out through said perforations in a shower as the wings pass over the vertex. The rear portions of the wings 0 are not perforated, for the reason that they then act to retain a portion of the hydrocarbon liquid until the vane 0 becomes more or less nearly level, when said liquid runs forward over the perforated surface of the vane, and maintains the shower until said vane again becomes nearly vertical and dips into the liquid mass at the bottom of the carbureter.

The modification shown in Figs. 3 and 4 consists of a lattice, E, of wire or other proper material, placed within the carbureter, said lattice being covered with a coating of some absorbent material, or such material as will retard the flow of the liquid hydrocarbon, such as thin cloth, &c. These lattice structures are useful in machines of large capacity. They expose a great expanse of surface to the pass ing air without materially. retarding its flow, and therefore enable a carbureter ofmoderate size to pass large volumes of air through it, and very rapidly, with a proper degree of impregnarlution and delivered in shower or spray to the current of air passing through the machine, as set forth.

2. A revolving carbureterprovided with internal perforated wings or vanes, 0, whereby portions of thcliquid hydrocarbon are taken up and delivered in shower or spray to the passing current of air, combined with an interior grating, E, the surface of which is covered with a thin absorbent coating, as and for the purpose set forth.
